§ 02 / About this part
What it is
The PARTS EUROPE STARTER YA/GG, electrical. Stocked by Iron Offroad, the UK MX hard parts specialist.
This starter motor fits Yamaha and GasGas models, replacing OEM 5UM-81890-00-00. It is located on the engine casing and is responsible for turning the bike over under load. Internal failure is common after seasons of hard use, especially if the bike has been submerged or ridden in deep mud. This unit matches the factory torque specs to ensure your bike fires up instantly. Check the condition of your starter gears and woodruff key during the swap to prevent future mechanical issues.
